Question

which of the following uses the preterit tense?
el bombero apagó un fuego grande.
nicolas estaba muy nervioso.
ella estaba sorprendida.

Explanation:

The preterit tense in Spanish refers to completed, one-time past actions.

1. "El bombero apagó un fuego grande": "apagó" is the preterit form of the verb apagar (to put out), describing a finished, single past action.
2. "Nicolas estaba muy nervioso" and "Ella estaba sorprendida": "estaba" is the imperfect form of estar, used for ongoing or background past states, not completed one-time actions.

Answer:

A. El bombero apagó un fuego grande.
